Touch-type input terminal apparatus for pointing or specifying position on display device
First Claim
1. An input terminal apparatus for inputting, to a display device which has a screen and displays input information on the screen, positional information indicating a display position of the input information displayed on the screen, said input terminal apparatus comprising:
- a touch sensor means including a sensor area having sensing points which number is less than the number of pixels of said screen, for detecting a touch condition on the sensor area per each of the sensing points, said touch condition comprising at least one of a touch pressure and a total touched area;
a detection result outputting means, which is coupled to said touch sensor means, for sampling the detected touch condition periodically at a predetermined time interval and outputting detection data indicating the detected and sampled touch condition as a detection result;
a memory means for storing the detection data outputted from said detection result outputting means; and
a calculating means for calculating a vector quantity of a movement of said display position on said screen corresponding to a movement of a sensing point touched on said sensor area, by calculating a direction of the vector quantity from a direction of said movement of the touched sensing point, and by calculating an absolute value of the vector quantity from a distance of said movement of the touched sensing point and the sampled touch condition, on the basis of the detection data stored in said memory means, and outputting movement data indicating the calculated vector quantity to said display device.

Abstract
An input terminal apparatus for inputting, to a display device which has a screen and displays input information on the screen, positional information indicating a position of the input information displayed on the screen, is provided with: a touch sensor device including a sensor area having sensing points which number is less than the number of pixels of the screen, for detecting a touch condition on the sensor area per each of the sensing points; and a detection result outputting device, which is coupled to the touch sensor device, for sampling the detected touch condition periodically at a predetermined time interval and outputting detection data indicating the detected and sampled touch condition as a detection result. The input terminal apparatus is also provided with: a memory device for storing the detection data outputted from the detection result outputting device; and a calculating device for calculating a vector quantity of a moving amount on the screen corresponding to a moving amount of the position touched on the sensor area, on the basis of the detection data stored in the memory device, and outputting movement data indicating the calculated vector quantity to the display device.
